Here we are given the specific equation of:
amount of eroded soil = 0.4 + 1.3 x
where x is the flow rate
A linear equation has a general formula in the form of:
y = m x + b
where m is the slope and b is the y intercept of the equation
If we compare this with our specific equation, we can see that the slope and y intercept are both positive with values:
m = 0.4
b = 1.3
Therefore this only means that as the flow rate increases, the amount of eroded soil also increases.
Hence the correlation must be positive but we cannot solve for the exact value since we need the data for x and y.
Answer:
positive, but we cannot say what the exact value is
The domain is the x values
y = 2 - x
when x = -3
y = 2 - (-3)
y = 2 + 3
y = 5....so ur points are (-3,5)
when x = -2
y = 2 - (-2)
y = 2 + 2
y = 4....so ur points are (-2,4)
when x = -1
y = 2 - (-1)
y = 2 + 1
y = 3...so ur points are (-1,3)
when x = 0
y = 2 - 0
y = 2....so ur points are (0,2)
when x = 1
y = 2 - 1
y = 1...so ur point are (1,1)
so basically, u plot all of those points
It would be 4x < h < 10x
the difference between 3x - 7x =4
and the sum would be 3x + 7x =10
Answer:
Simplifying
3n + 7 = 30
Reorder the terms:
7 + 3n = 30
Solving
7 + 3n = 30
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + 3n = 30 + -7
Combine like terms: 7 + -7 = 0
0 + 3n = 30 + -7
3n = 30 + -7
Combine like terms: 30 + -7 = 23
3n = 23
Divide each side by '3'.
n = 7.666666667
Simplifying
n = 7.666666667
